Title: Manufacture of variable capacitance diode
Inventor: MIYAGAWA YOSHIHIDE
IPC: H01L29/93
Filed: 1997-01-14
Abstract: PROBLEM TO BE SOLVED: To allow easier manufacture by forming, on the upper surface of a semiconductor layer, a dummy layer of heat-resistant insulation material, and ion-implanting impurities in the semiconductor layer through the dummy layer. SOLUTION: On one surface of a substrate 1, a semiconductor layer 2 of, for example, GaAs is formed by an epitaxial growth method. Such impurity as silicon is added in low concentration to the semiconductor layer 2, for giving semi-insulation characteristics. After the semiconductor layer 2 grows to a specified thickness, a dummy layer 5 is applied on the surface of the semiconductor layer 2 by sputtering, etc. As the dummy layer 5, such heat-resistant insulation material as silicon dioxide is used. Although the film thickness of the dummy layer 5 is specified by an acceleration voltage at ion-implantation or the material of dummy layer 5, such film thickness as the impurity concentration at ion-implantation becomes maximum at the joint surface between the dummy layer 5 and the semiconductor layer 2 is set.  Thus, such a semiconductor layer 2 with pseudo super-step characteristics wherein impurity concentration becomes lower in the depth direction is provided.

Title: Activity promoter for glutathione reductase
Inventor: IWATA SHUZO
IPC: C12N9/06
Filed: 1988-01-14
Abstract: PURPOSE:To obtain an activity promoter for glutathione reductase useful for senile cataract, corneal ulcer, etc., containing pyrroloquinoline quinones as an active ingredient and having activity promoting action on the glutathione reductase. CONSTITUTION:An activity promoter containing pyrroloquinoline quinone [another name; 2,7,9-tricarboxy-1H-pyrrolo(2,3-f)quinoline quinone-4,5-dione] as an active ingredient. Reduced form glutathione is extensively present in animal tissues and has function of enzymically and nonenzymically reacting with proteins or other disulfides, maintaining SH groups thereof, etc. The reduced form glutathione is converted into oxidized form glutathione after action in living bodies. The resultant oxidized form glutathione is then substantially irreversibly reduced into the reduced form glutathione by glutathione reductase while reduced form nicotinamide adenine dinucleotide (phosphate) [NAD(P)H] is participating therein. The above-mentioned active ingredient provides effects similar to those by addition of the reduced form glutathione.

Title: Honeycomb structure combustion catalyst
Inventor: IMAI TETSUYA
IPC: B01J35/02
Filed: 1994-01-21
Abstract: PURPOSE:To prevent overheating of walls of a catalyst and enhance the combustion efficiency by using plural numbers of honeycomb structure units in which at least one passage for fluid adjacent to a passage for fluid having an active material does not have an active material and arranging these units in such a manner that the amt. of active material for each unit is equal. CONSTITUTION:The combustion catalyst 1 having a honeycomb structure is formed by arranging plural numbers of honeycomb structure units A1-B1. Each unit has cells 1 having an active material 2 which causes the catalytic reaction as passages for fluid and cells 3 having no active material 2. At least one adjacent cell to the cell 1 is the cell 3. These units are arranged in such a manner that the amt. of the active material 2 in cells for each unit is equal. When a combustible gas preliminarily mixed is supplied to cells having the active material 2, the combustion reaction proceeds to heat the walls in contact with the gas. However, since the adjacent cell 3 has no active material 2, the combustion reaction does not proceed but the contact wall is cooled with the gas. Thus, even when contact combustion is performed, overheating of contact walls is prevented. By arranging cells 1 and cells 3 so as to make a uniform gas flow, the combustion efficiency can be enhanced.
